摘要：Environmental pollution affects the quality of atmosphere, lithosphere and biosphere. Efforts have been made in the last two decades to reduce the pollution sources and remedy the polluted water sources. Water quality monitoring in developing countries is inadequate especially in stream water affected by urban effluent and runoff. The purpose of this study was to investigate heavy metal contaminants in sank stream water in Gwalior. The water sample from stream and industrial effluents that drain into the stream were collected and analyzed for the total elemental concentration using atomic absorption spectrophotometer. The result showed that:-the wastewater was highly encircled with copper above the maximum permissible limit. 2) the level of dissolved oxygen was below the maximum permissible limit, while biological oxygen demand was above the maximum permissible limit. All industrial effluents/wastewater were classified as strong. Factors analysis results reveal two sources of pollutants; multiple origin of copper and mixed origin or chemical phenomena of industrial and vehicular emission.
